If I do it, I guess I’ll just reassess my options at that point. I’m also struggling with heavy periods on oral progesterone (and estradiol patches).
For anyone currently on mirena—have you experienced any side effects?
Five years is outdated information. The mirena IUD has been approved for preventing pregnancy for up to eight years. It was recently approved in the US a couple of years ago but it’s been approved for this length in Europe for over a decade. Several large scale studies show that there is significant protection for preventing pregnancy up to eight years.
Progesterone is still active after year five. There is a different IUD, the Lyleta I believe it’s called, that is only approved for five years. It sounds like your doctor is confused.
But yes, I have had Mirena in for many years, I’m on my second, and I have never noticed any side effects. It is not particularly fun to get it in and out, but I had had two vaginal births by the time I got my first one and so it was manageable. Some doctors will numb you as well if that’s something you would prefer. I highly recommend it.
